New to music, searching for good portable digital organ / piano / keyboard

Hi. I am trying to steer my kids into learning more about music and making it, for homeschool and family education. I am leaning toward buying two digital pianos or keyboards that are portable and have these features if possible to have all of them. When I look online I see all types available and I haven't found a good place that tells me comparisons so I know how one is different from the other, benefits, etc.

Would anyone be able to suggest a digital portable piano keyboard with all of these features I list below? I would buy two of them so my kids and I can both share to learn and compose music as a hobby. I'd like to stick to $1,000 each. And maybe I should not buy two of the same, due to some reasons I'm not aware of? If you think it would be best to buy two different portable digital pianos, please let me know and why.

After they learn enough musical talent I don't want to limit the kids from being able to play a real piano but I also don't honestly think any are going to go that route. So whatever features can mimic that of a full sized piano I'd like to have on the digital keyboards I buy, but this isn't necessary.

Thanks!

Features to have:
1. 88 keys
2. built in digital recorder
3. built in speakers
4. portable
5. under $1,000 each
6. play many or most sounds of other instruments and several dozen voices
7. split key?
8. can talk to computer via USB or other means
9. mixing capability of sound from externally recorded sources?

I'm in the Province of Ontario, in Canada, and in all realities, there really is only one choice.
And that comes down to getting it all for the lowest price.
The government of Ontario, in 1971, sold out all Ontario musical manufacturers and franchises,
everything from acoustic pianos, symphony and marching band instruments, to electric guitars and amps.
They let Yamaha move in, replacing all the instruments in government buildings and schools.
Yamaha would pay to change the signage for music stores, if you bought into their franchise.
So for sure, anything Yamaha has the lowest price, and just as importantly,
you're probably plugging it into more Yamaha equipment.

How pervasive is Yamaha?
In the last two years, the only time I've ever found an acoustic guitar in a case in a residential dumpster,
and that's twice, were Yamahas, both in excellent condition.
Musicians stopped saying Yamahaha a long time ago.
